The getBindings() method of a SimpleScriptContext class is used to return the bindings associated with the given scope in this ScriptContext where scope is passed as parameter.
Syntax:
Bindings getBindings(int scope)
Parameters: This method accepts a single parameter scope which is the scope in this ScriptContext.
Return value: This method returns associated Bindings and returns null if it has not been set.
Exceptions: This method throws following Exceptions:
- IllegalArgumentException: If no Bindings is defined for the specified scope value in ScriptContext of this type.
Below programs illustrate the SimpleScriptContext.getBindings() method:
Program 1:
// Java program to demonstrate// SimpleScriptContext.getBindings() method  import javax.script.Bindings;import javax.script.ScriptContext;import javax.script.SimpleScriptContext;  public class GFG {    public static void main(String[] args)    {          // create SimpleScriptContext object        SimpleScriptContext simple            = new SimpleScriptContext();          // add some attribute        simple.setAttribute(            "name1",            "Value1",            ScriptContext.ENGINE_SCOPE);        simple.setAttribute(            "name2",            "Value2",            ScriptContext.ENGINE_SCOPE);          // get bindings using getBindings()        Bindings bindings            = simple.getBindings(                ScriptContext.ENGINE_SCOPE);          // print        System.out.println("Bindings value for name1:"                           + bindings.get("name1"));        System.out.println("Bindings value for name2:"                           + bindings.get("name2"));    }} |
Output:
Bindings value for name1:Value1 Bindings value for name2:Value2
Program 2:
// Java program to demonstrate// SimpleScriptContext.getBindings() method  import javax.script.Bindings;import javax.script.ScriptContext;import javax.script.SimpleScriptContext;  public class GFG {    public static void main(String[] args)    {          // create SimpleScriptContext object        SimpleScriptContext simple            = new SimpleScriptContext();          // add some attribute        simple.setAttribute(            "Team1",            "India",            ScriptContext.ENGINE_SCOPE);        simple.setAttribute(            "Team2",            "Japan",            ScriptContext.ENGINE_SCOPE);        simple.setAttribute(            "Team3",            "Nepal",            ScriptContext.ENGINE_SCOPE);          // get bindings using getBindings()        Bindings bindings            = simple.getBindings(                ScriptContext.ENGINE_SCOPE);          // print        System.out.println("Bindings value for Team1:"                           + bindings.get("Team1"));        System.out.println("Bindings value for Team2:"                           + bindings.get("Team2"));        System.out.println("Bindings value for Team3:"                           + bindings.get("Team3"));    }} |
Output:
Bindings value for Team1:India Bindings value for Team2:Japan Bindings value for Team3:Nepal
